DISINTEGRATING-MAOHINE.

Specification of Letters Patent. Application filed April 5, 1913.

Patented Dec. 39, 1913. Serial No. 759,126.

To all whom it may concern:

Be it known that 1, ROBERT F. W. Rossnnne, a citizen of the UnitedStates, residing at East Helena, in the State of Montana, have inventedcertain new and useful Improvements in Disintegrating-Machines, of

'which the following is a specification.

My invention relates particularly to improvements in disintegrating andcrushing machines for crushing rock, ore or similar substances, andrelates particularly to machines in which the crushing is performed byrollers, which are yieldingly held in adjusted position with relation toeach other, in order to crush the material to predetermined size.

he primary object of this invention is to provide means whereby thecrushing rollers may be speedily adjusted to crush material to differentsizes, without varying the resistance of the rollers to abnormalpressure.

The further be more fully set forth in one form of apparatus embodyingmy invention, which consists in the new and novel features ofconstruction and after set forth and claimed.

Inthe accompanying 1 is a plan View of a disintegrator embodying myimprovement. Fig. 2 represents a side elevation of the same. Fig. 3 is adetail view of the adjusting lever.

Referring to the particular mechanism shown in the accompanyingdrawings, the rollers 1, 2 are mounted in suitable bearings provided inthe frame 3 and are rotated in any suitable manner, as by a pulley 4,which may be connected with a suitable source of power. The material isfed through a hopper 5 supported on the frame immediately above therollers. One of said rollers, for example, the roller 1, is mounted infixed bearings and the other roller 2 is mounted in bloclrs 6 movable onthe guides 7 formed in the frame. A plurality of arms 8 are se cured tothe shaft of said roller and are mounted in a cross bar 9. Said arms areadjustably held in said cross bar by means of nuts 10 secured upon theouter end of each arm. A spring 11 is mounted on each arm approximatelya between said bar and a collar 12, formed in tegral with the arm.

The cross bar 9 is connected to a plurality of upright levers 14 bymeans of a plurality of adjustable links 15. Said levers are pivoted tobrackets 16 rigidly secured to the objects of the invention willcombination of parts herein-V drawings :Figure frame and are connectedat or near their tops by a cross brace 17. The levers are held inposition by a suitable locking frame 18 which comprises the side pieces19, each having a plurality of corresponding notches at or hear theirouter ends, said side pieces being connected together and held inpermanent relation to each other by the cross brace 20. Said notches areadapted to engage with suitable extensions or cap screws 21 providedupon the levers. The side pieces of said frame rest in suitable recessesprovided in the frame 3 of the machine, so as to hold the levers againstdisplacement, said side pieces 19 being securely held in position withrelation to the levers 14 by means of the cap screws 21 which havethreaded engagement in the levers, the shanks of said screws beingreceived in the notches provided in the pieces 19. i

In operation, the rollers are adjusted with relation to each other bymoving the operating levers 14 toward or from their vertical positions,which actuates the transverse bar 9 and through it moves the arms 8attached to the crushing roller 2, thus causing the bearings of saidroller to move in their guides. After being adjusted the rollers arelocked in position by means of the locking device, which is caused to beengaged with the cap screws 21 provided upon the levers. Vhile thenormal distance between the rollers is thus established, it is obvious,however, that a slight yielding movement of the rollers with relation toeach other, independent of the adjusting levers, is permitted by thetension springs 11 which are mounted on the arms between the collars 12provided thereon and the transverse bar. The proper tension of thesesprings may be determined for all positions of the roller 2 and is notaffected or modified in any way whatever by the adjustment of therollers toward or away from each other by means of the adjusting lever.V

y means of this construction, a speedy and rapid adjustment of therollers may be made to crush material of difierent predetermined sizesby releasing thelocking frame and actuating the adjusting levers. Thelocking frame and the levers form a truss that is extremely rigid, butpermits of speedy adjustment. The tension springs, when once adjusted,are not disturbed in any way by the movement of the rollers toward andaway from each other and both the locking device and the adjustinglevers are connected together, so as to permit simultaneous operationwith a minimum of effort.

Although I have shown and described one form of mechanism embodying myinvention, it is obvious that various changes within the knowledge ofthose skilled in the art may be made without departing from the spiritof the invention, provided the means cable roller 111 its adjustedposition, and

means connecting said lever to said bar and permitting of the adjustmentof the bar with relation to the lever.

2. In a disintegrating machine, a pair of crushing rollers, movablebearings for one of said rollers, arms connected to said bearings, a bararranged in parallel relation to the axis of said roller and adjustableupon said arms, spaced connecting levers, and means connecting therespective levers to said .bar adjacent its ends but permitting of theadjustment of said bar with respect to the levers.

3. In a disintegrating machine, a pair of crushing rollers, movablebearings for one of said rollers, a bar arranged in parallel relation tothe aXis of the roller, armsconnected to the respective bearings andextending loosely through openings in the ends of-said bar, nutsthreaded upon the arms bearing against said bar to adjust the same withrelation to the roller, springs arranged upon said arms and tensioned bythe bar, and means for locking theb-ar in its adjusted position. 1

4. In a disintegrating machine, a pair of crushing rollers, movablebearings for one of said rollers, arms connected to the respectivebearings, springs arranged upon said arms, a bar longitudinallyadjustable upon the arms to tension said springs, a pair of levers,members pivotally connected to one end of said levers,said members beingloosely disposed through said bar, means for securing the bar in itsadjusted position upon said members, and additional means I to lock thelevers against movement and retain said bar in its adjusted position.

This specification signed and witnessed this 27 day of March A. D.,1913.
